Roller system used for robot intelligent rolling and edge-covering system

Abstract

The invention discloses a roller system used for a robot intelligent rolling and edge-covering system. The roller system comprises a robot connecting flange, wherein the lower end surface of the robot connecting flange is connected to a main shaft; the tail end of the main shaft is provided with a rolling head; the rolling head is provided with a plurality of rollers; a pressure sensor and a drive spring are arranged inside the main shaft; the pressure sensor is used for detecting and monitoring pressure of the drive spring; the drive spring is connected to the rolling head for directly reflecting working pressure, acting to a workpiece, of the rolling head, so that rolling and edge-covering quality is guaranteed. In addition to normal rollers, the rolling head further comprises a cover-covering knife which can be used for carrying out blank pressing on a sharp corner during rolling of automobile inner and outer plates. According to the roller system, after the rollers are pressed on a turned part, extrusion is caused to a compression elastic part, so that the compression elastic part generates pressure on the rolling head, a rollover working part can reach practical needed rolling force by only needing to control deformation amount of the compression elastic part, so that rollover quality is guaranteed, and the problem that a conventional roller system is liable to generate a stacking and wrinkling problem during blank pressing at the sharp corner part is solved.

Description

technical field [0001] The invention relates to a mechanical device, more specifically, to a roller system used in a robot intelligent rolling hemming system. Background technique [0002] With the increasingly fierce market competition, the continuous shortening of the automobile development cycle, and the continuous emergence of new models, the flexible and reconfigurable body production line technology is a new production mode developed for the production needs of small batches and multiple varieties in today's manufacturing industry. One of the key elements to shorten the automobile development cycle and improve product competitiveness. [0003] The robot hemming system can adapt to different characteristics of the work by making corresponding changes to the work program for different workpieces. When facing different processed parts, it can smoothly move along the contour of the workpiece to perform rolling hemming motion. It overcomes the problems that the hydraulic m...

[0005] On the other hand, the current common roller system is composed of rollers of various shapes. ) The hemming angle caused by the hemming track of the robot has a great influence. For example, the roller system cannot be used for hemming at sharp corners, that is, 0° hemming, which needs to be completed by using a special push angle mechanism. If the hemming is forced, such piles will appear material phenomenon and cause poor quality, etc.
